This 5.12ct lab-grown radiant sits in the over five carat band, graded F colour (colourless) and VS2 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG603343421 or 603343421. Listed at 16 retailers as of October 28, 2026, with prices from $990 to $6,100, a $5,110 spread on the same certified stone. Brilliant Earth lists it at $6,100. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
